Problem: Extended characters outside of ASCII range where not displayed
properly in SHOW PROCESSLIST, because thd_info->query was always sent as 
system_character_set (utf8). This was wrong, because query buffer
is never converted to utf8 - it is always have client character set.

Fix: sending query buffer using query character set

  @ sql/sql_class.cc
  @ sql/sql_class.h
    Introducing a new class CSET_STRING, a LEX_STRING with character set.
    Adding set_query(&CSET_STRING)
    Adding reset_query(), to use instead of set_query(0, NULL).

  @ sql/event_data_objects.cc
    Using reset_query()

  @ sql/log_event.cc
    Using reset_query()
    Adding charset argument to set_query_and_id().

  @ sql/slave.cc
    Using reset_query().

  @ sql/sp_head.cc
    Changing backing up and restore code to use CSET_STRING.

  @ sql/sql_audit.h
    Using CSET_STRING.
    In the "else" branch it's OK not to use
    global_system_variables.character_set_client.
    &my_charset_latin1, which is set in constructor, is fine
    (verified with Sergey Vojtovich).

  @ sql/sql_insert.cc
    Using set_query() with proper character set: table_name is utf8.

  @ sql/sql_parse.cc
    Adding character set argument to set_query_and_id().
    (This is the main point where thd->charset() is stored
     into thd->query_string.cs, for use in "SHOW PROCESSLIST".)
    Using reset_query().
    
  @ sql/sql_prepare.cc
    Storing client character set into thd->query_string.cs.

    Using CSET_STRING to fetch and send charset-aware query information
    from threads.

  @ storage/myisam/ha_myisam.cc
    Using set_query() with proper character set: table_name is utf8.

Problem: crash in Item_float constructor on DBUG_ASSERT due

Use __builtin_stpcpy only if the system supports stpcpy.
This is necessary as in some cases a call to stpcpy will
be emitted if the built-in can not optimized.

Memory was allocated for storing path names inside
fn_expand(), which were not free:ed anywhere.

This patch fixes the problem by storing the path
names in statically allocated buffers instead,
which is automatically free:ed when the server
exits.

Including adding test in 5.5 requiring --big-test
flag from mysql-test-run.pl and also disabled
tests that fails.

           during EXPLAIN

Before the patch, send_eof() of some subclasses of 
select_result (e.g., select_send::send_eof()) could 
handle being called after an error had occured while others 
could not. The methods that were not well-behaved would trigger
an ASSERT on debug builds. Release builds were not affected.

Consider the following query as an example for how the ASSERT
could be triggered:

A user without execute privilege on f() does
   SELECT MAX(key1) INTO @dummy FROM t1 WHERE f() < 1;
resulting in "ERROR 42000: execute command denied to user..." 

The server would end the query by calling send_eof(). The 
fact that the error had occured would make the ASSERT trigger. 

select_dumpvar::send_eof() was the offending method in the
bug report, but the problem also applied to other 
subclasses of select_result. This patch uniforms send_eof() 
of all subclasses of select_result to handle being called 
after an error has occured. 

The test result differs on windows, since
it writes out 'localhost:<port>' instead of
only 'localhost', since it uses tcp/ip instead
of unix sockets on windows.

Fixed by replacing that column.

Also requires --big-test from some long running tests
and added a weekly run of all test requiring --big-test.

Problem:  with "make package" , many small packages are 
generated, one per CMake COMPONENT, instead of expected single
package. This is due to the new (in cmake 2.8.3) component-based 
install for archive( e.g ZIP,TGZ ) CPack generators.

See http://public.kitware.com/Bug/view.php?id=11452 for discussion.

Fix: use CPACK_MONOLITHIC_INSTALL=1 to enforce single package.

structure buffer).

This is a follow-up for WL#4435. The bug actually existed not only
MYSQL_TYPE_DATETIME type. The problem was that Item_param::set_value()
was written in an assumption that it's working with expressions, i.e.
with basic data types.

There are two different quick fixes here:
  a) Change Item_param::make_field() -- remove setting of
     Send_field::length, Send_field::charsetnr, Send_field::flags and
     Send_field::type.

     That would lead to marshalling all data using basic types to the client
     (MYSQL_TYPE_LONGLONG, MYSQL_TYPE_DOUBLE, MYSQL_TYPE_STRING and
     MYSQL_TYPE_NEWDECIMAL). In particular, that means, DATETIME would be
     sent as MYSQL_TYPE_STRING, TINYINT -- as MYSQL_TYPE_LONGLONG, etc.

     That could be Ok for the client, because the client library does
     reverse conversion automatically (the client program would see DATETIME
     as MYSQL_TIME object). However, there is a problem with metadata --
     the metadata would be wrong (misleading): it would say that DATETIME is
     marshaled as MYSQL_TYPE_DATETIME, not as MYSQL_TYPE_STRING.

  b) Set Item_param::param_type properly to actual underlying field type.
     That would lead to double conversion inside the server: for example,
     MYSQL_TIME-object would be converted into STRING-object
     (in Item_param::set_value()), and then converted back to MYSQL_TIME-object
     (in Item_param::send()).

     The data however would be marshalled more properly, and also metadata would
     be correct.

This patch implements b).

There is also a possibility to avoid double conversion either by clonning
the data field, or by storing a reference to it and using it on Item::send()
time. That requires more work and might be done later.

      MySQL-shared RPM no longer provides mysql-shared

The spec file is changed to explicitly "provide" "mysql-shared"
by the "shared" sub-RPM.

Backport version info handling  (Windows-specific) from next-mr. 
Instead of adding ".res" object as linker flag, add  resource file (.rc) file to the source list.
This is more obvious and less error prone method.

Before this fix, file io for the binary log file was not accounted properly,
and showed no io at all.

This bug was due to the following issues:

1) file io for the binlog was instrumented:
- sometime as "wait/io/file/sql/binlog"
- sometime as "wait/io/file/sql/MYSQL_LOG"
leading to inconsistent event_names.

2) the binlog file itself was using an IO_CACHE,
but the IO_CACHE implementation in mysys/mf_iocache.c was
not instrumented to make performance schema calls to record file io.

3) The "wait/io/file/sql/MYSQL_LOG" instrumentation was used
for several log files, such as:
- the binary log
- the slow log
- the query log
which caused file io in these different log files to be accounted
against the same instrument.
The instrumentation needs to have a finer grain and report io
in different event_names, because each file really serves a different purpose.

With this fix:
- the IO_CACHE implementation is now instrumented
- the "wait/io/file/sql/MYSQL_LOG" instrument has been removed
- binlog io is now always instrumented with "wait/io/file/sql/binlog"
- the slow log is instrumented with a new name, "wait/io/file/sql/slow_log"
- the query log is instrumented with a new name, "wait/io/file/sql/query_log"
